Abstract: An electronic flash device which is protected from thermally damaging a lamp holder (30) supporting a flash tube (40) even when the flash tube is lighted in a consecutive manner for a prolonged period of time. The lamp holder is made of ceramic material. The flash tube is supported by the lamp holder via a tube mounting member (44) which includes a wavy central part (44A) extending laterally along a back side of the lamp holder and a pair of annular parts (44B) fitted on either axial end of the flash tube such that the flash tube is resiliently urged against a bottom part of a concave mirror (42) received in the lamp holder.

Abstract: A strobe device configured to be connectable with an external power supply device to receive electric power for light emission from outside, includes: a main capacitor for storing electric charge for light emission; an internal power supply for supplying electric power to the main capacitor; and a power supply control unit configured to control supply of electric power to the main capacitor. The power supply control unit is configured to determine whether electric power is being supplied to the main capacitor from outside based on a change in a charge state of the main capacitor after a discharge of the main capacitor for light emission, and when it is determined that electric power is being supplied from outside, prevent the internal power supply from supplying electric power.
